Ancient Beckoning

The Ancient Beckoning area of the Secret Realm contains five unwinnable boss battles that allow you to farm Mastery Stones used to give flat increases to your heroes' stats. The goal is to deal as much damage as possible within 99 turns. Each boss is available for 6 days and is cycled sequentially.

Rewards[]

After you challenge an Ancient Beckoning boss, you are are given a score individually based on the damage you deal. These scores and your rank determine the rarity of the 60 Mastery Stones you will obtain at the end of each 6-day cycle. You are also ranked against other players on your server. This ranking determines the number and rarity of the Arena Mastery Stones you will gain and the end of each 30-day cycle.
